Gas meter is clocking incredibly high usage with no one in the house?

We have been seeing incredibly high gas usage for the last few months or so, even when no one is in the house. We’ve not even had our heating on yet and it’s mid December because we are so concerned about the usage clocking up just using the boiler for hot water. For example on Sunday no one was home between the hours of 4.30pm-11.30pm and we clocked up around 60kwh of usage according to the OVO app:

For reference I live in a moderately sized 4 bedroom flat, in a block of 5 flats. We are currently only using the gas for hot water for showers or washing up.

Temperatures are now below freezing so we want to put our heating on but with the extra usage clocking up our bill is already unmanageable and we are lost at what to do next. Can anyone offer any advice?

@epwg I’ve been looking back through the detail here and think there’s a distinct possibility either that there’s a leak (which would need looking at very quickly) or you are seeing usage reading from another property. Is there a possibility of you switching your gas off or are you absolutely sure there’s nothing using any gas?

 

Another option is to check your actual meter readings over a day and that can be compared with the kWh being reported. 


Just looking at the half-hourly readings you’ve posted and it really looks like a high use over those times, somewhat akin to a boiler switching on for a while. 


The cold weather can affect pipe work and so it could be a leak expanding and contracting but I’m not sure it would be on that.

 

 You can find a guide for checking your usage data on the app here:

Hey @Giorgya,

 

Sorry for the issues you’re having,

 

When a meter exchange takes place the engineer will make a note of the removal reading of the old meter, you’ll get a final bill for that meter. Then make a note of the install read of your new meter, you’ll be billed from this reading. There should be a white or yellow sticker on the meter with these readings. 

 

If you’re concerned your meter is clocking to fast, these topic’s may help:

 

 

If you smell gas or thin you have a leak:

 

Call the 24-hour National Gas Emergency service on 0800 111 999

  • Do open doors and windows to let the gas out

  • Do check your gas appliances are switched off

  • Do turn your gas off at the isolation switch (if you know where it is)

  • Do wait outside your home, and let your neighbours know#

  • Don't use any electrical switches, and don't switch lights on or off

  • Don't smoke, light a match, or use any other kind of naked flame

  • Don't go back into your home until you've got the all-clear

 

Signs of a gas leak

  • Strong smell of gas in your home

  • The pilot light on your boiler frequently blows out

  • Pilot light or gas rings on your cooker are orange or yellow, rather than crisp blue

  • Soot or scorched areas on the exterior of appliances

  • More condensation than usual on windows

I’ve just been away for ten days and turned my heating/hot water off. Suddenly two days before I got back and turned the system on again I’m shown as having used as much gas and electricity as I do when I’m at home. How come? It’s been mild so no weather responses kicking in.

I’ve been away for ten days and turned my system off. On return I see the smart meter has recorded normal usage for two days of my absence then gone back to minimal. Does it feel obliged to top up ovo earnings?

Probably an estimate.

Sometimes if the collected smart meter readings show a full day of no use - as could happen if you have turned everything off - the “live billing” system can assume that the meter hasn't connected to DCC to send readings, and so it puts in an estimated usage for that day.

Your actual billing uses the meter readings at the start and end of your billing period each month; so some missing reads or odd estimates in the middle of the billing period will be rectified and will not be a problem.

Sorry to waste your time. As a first time user it was hard to work out where to post my question. The site is noisy and somewhat off putting. I think next time I’ll dodge reproofs and wait for ovo to answer the phone.

I've answered in the other thread that you started.

PS.There is no need to ask the same question in two places, one is enough for the staff and forum regulars to pick a question up and reply.

Morning ​@Alisonbrimelow and a warm welcome to the OVO Forum.

 

This is definitely something the community can help out with, but we’ll need to get some more info from you. Just to confirm - smart meters send your readings automatically, and it’s incredibly rare they clock usage incorrectly. 

 

We’ll need to know:

 

Are you referring to gas or electricity?

 

Where have you seen this - was it on the In Home Display (IHD), or on the ‘Usage’ pages of your online account / app?

 

If it was on the ‘Usage’ pages, please could you send a screenshot of what you’re looking at?

 

If you send any screenshots of the online account / app, please ensure that any personal details aren’t included, eg your account number.

 

Once we have this info we’ll be able to help further.
